Subject: [PATCH] mailbox: PCC: erroneous error message when parsing ACPI PCCT
There have been multiple reports of the following error message:
[ 0.068293] Error parsing PCC subspaces from PCCT
This error message is not correct. In multiple cases examined, the PCCT
(Platform Communications Channel Table) concerned is actually properly
constructed; the problem is that acpi_pcc_probe() which reads the PCCT
is making the assumption that the only valid PCCT is one that contains
subtables of one of two types: ACPI_PCCT_TYPE_HW_REDUCED_SUBSPACE or
ACPI_PCCT_TYPE_HW_REDUCED_TYPE2. The number of subtables of these
types are counted and as long as there is at least one of the desired
types, the acpi_pcc_probe() succeeds. When no subtables of these types
are found, regardless of whether or not any other subtable types are
present, the error mentioned above is reported.
In the cases reported to me personally, the PCCT contains exactly one
subtable of type ACPI_PCCT_TYPE_GENERIC_SUBSPACE. The function
acpi_pcc_probe() does not count it as a valid subtable, so believes
there to be no valid subtables, and hence outputs the error message.
An example of the PCCT being reported as erroneous yet perfectly fine
is the following:
Signature : "PCCT"
Table Length : 0000006E
Revision : 05
Checksum : A9
Oem ID : "XXXXXX"
Oem Table ID : "XXXXX "
Oem Revision : 00002280
Asl Compiler ID : "XXXX"
Asl Compiler Revision : 00000002
Flags (decoded below) : 00000001
Platform : 1
Reserved : 0000000000000000
Subtable Type : 00 [Generic Communications Subspace]

Address : 0000000000001842
Preserve Mask : 00000000000000FD
Write Mask : 0000000000000002
Command Latency : 00001388
Maximum Access Rate : 00000000
Minimum Turnaround Time : 0000
To fix this, we count up all of the possible subtable types for the
PCCT, and only report an error when there are none (which could mean
either no subtables, or no valid subtables), or there are too many.
We also change the logic so that if there is a valid subtable, we
do try to initialize it per the PCCT subtable contents. This is a
change in functionality; previously, the probe would have returned
right after the error message and would not have tried to use any
other subtable definition.
Tested on my personal laptop which showed the error previously; the
error message no longer appears and the laptop appears to operate
normally.
